A TTOR/VE V EDWARD J. GRUIBEN, OF ROYSTON, TEXAS.

PLANTER.

Specification of Letters Patent.

Patented J an. 16, 1917.

Application filed April 4-, 1916. Serial No. 88,916.

To all whom it may concern Be it known that I, EDWARD J. GRUBEN,

a citizen of the United States, residing at Royston, in the county ofFisher and State of Texas, have invented certain new and usefulImprovements in Planters, of which the following is a specification.

This invention pertains to new and useful improvements in planters.

Various means and methods have been evolved and used for plantingstraight rows, but require more or less preparatory or mechanical workin every case.

It is the purpose of my invention to provide a planter by which thegrain may be planted in a straight row and in which the foot or shovelmay be guided by a swaying movement of the driver.

In carrying out the invention the mast on which the foot or shovel iscarried is mounted in a roller guide frame and constructed to easilyrotate. A swinging seat member is mounted on the frame and connectedwith the mast so that when the seat is swung to one side the mast willbe rotated and the point of the shovel moved in the desired direction.

In planters now in common use the constructlon is invariably such thatthe elevating or plow raising lever is raised when the plow is lowered,said lever being constantly in the way of the driver. My invention alsocontemplates a construction whereby this lever is lowered to lower theplow or shovel and remains in a horizontal position during the plantingoperation.

Other objects will be apparent from a perusal of the followingspecification and the invention will be more readily understood byreference to the accompanying drawings, wherein:

Figure 1 is a plan View of a planter equipped with my invention, Fig. 2is a side elevation of the same, certain parts being omitted and othersindicated as broken away to show component parts, and Fig. 3 is a detailof the roller guide frame and'adjusting means for the mast.

In the drawings the numeral 1 designates a horizontal frame attached toa tongue 2 at its forward end and carrying a cross-bar support 3 at itsrear end; while similar sup ports 4: and 5 respectively, are disposedforward and rearward of the aXle 6. The forward support 5 is enlarged atits center to permit a vertical mast 7 to pass therethrough. This mastcarries the usual shovel or plow 8 at its lower end and is shown in Fi 2in its raised position.

tandards 9 secured to the cross bar 5 support vertical shafts 10carrying rollers 11 on their upper ends and rollers 12 on their lowerends. The lower rollers 12 rest on the cross-bar 5. These rollers ofwhich four upper and four lower are shown, bear against the mast atequidistant points. The mast being cylindrical may be easily rotated,the rollers reducing the friction to a minimum. By observing Fig. 2 itwill be seen that a slight partial rotation of the mast will swing thepoint of the shovel to either side of the center of the planteraccording to the direction of rotation of the mast.

For rotating the mast the seat 13 is arranged to swing. The seat ismounted on the upper end of a rearwardly inclined seat bar 1i having itslower end pivoted on the bar 4. An angular arm 15 depends from the seatbar and has a roller 16 mounted on its lower end. This roller travels onthe bar 3 which has an arcuate portion forming a track for said roller.A connecting bar 17 is centrally pivoted on a bolt 18 passing throughthe seat and seat bar. This bar 17 extends transversely of the frame andhas its outer end pivoted to the rear end of parallel lengths 19extending forward and pivoted on vertical rods 20 fastened be tween arms21 projecting laterally from the mast. As indicated by the dotted linein Fig. l the mast is rotated and the parts angularly displaced when theseat is swung to one side; the swinging movement of the seat beingcommunicated to the mast through the agency of the parts 17 19, 20 and21.

It is pointed out that the slightest lateral adjustment of the plowpoint 8 will cause the wheels and the whole frame to immediately follow;thus the seed tube will drop seed in the furrow and in the proper place.

A yoke 22 supports the links and is provided with a central dependingshank 23 which is fastened to the rear standard 9. This yoke permits thelinks to be swung and supports them at the same elevation irrespectiveof the adjustment of the mast, the rods being free to slide through theends of the links. A cap 24 is mounted on the upper end of the mast andrests on a collar 25 clamped about the said mast and having forwardlyprojecting cars 26. The upper arms 21 are mounted on the mast. Avertical link 27 has its upper end pivoted between the ears and itslower end pivoted in a crank arm 28 projecting rearwardly from a rockshaft 29 mounted on the frame and having one end supported in a segmentbracket 30 which cooperates with an elevating lever 31 fastened on theshaft. This lever has a spring pressed locking plunger 32 engaging thebracket 30. The lever is made to serve the double purpose of elevatingthe mast and shifting the clutch of the seed dropping mechanism and withthe shovel elevated and the dropping mechanism unclutched, the leveroccupies an angular position of about. forty-five degrees to theperpendicular. The usual clutch sleeve 33 is mounted on theaXle 6 toengage with mechanism (not shown) mounted under the seed can 34: andforming no particular part of this invention.

A clutch lever 35 is pivoted on an arm 36 projecting inward from theframe 1 and has its rear end attached to a coiled spring 37 which isalso fastened to the frame. The forward end of the lever is forked andembraces the sleeve 33 to which it is pivoted in the usual manner. Theforked end of the lever is connected with the end of a chain 38 whichpasses over a pulley 39 mounted in a. bracket 40 projecting from theframenear the said end of the lever. The chain extends upward and isattached to the lever 31 as shown.

It is apparent that when the lever is swung downward the chain isslackened whereby the spring 37 swings the lever 35 and shifts theclutch sleeve 33 into engagement with the dropping mechanism; while atthe same time the shaft 29 is rocked so that the arm 28 is swungdownward whereb the link 27 is carried downward which results in thelowering of the mast and the opener attached to said mast, a seeddropping clutch mechanism, an adjusting lever having connection with themast foradjusting the same and also connected with the clutch mechanismfor shifting the same, and means for rotating the mast.

3. In a planter, a vertical mast, a furrow opener attached to said mast,a roller guide frame in which the mast is both rotatable and slidablevertically, a swinging seat, and a rotating structure connected with theseat and also with the mast for rotating the latter, said structurebeing supported in a fixed horizontal position, the mast being slidablyconnected therewit 4. In a planter the combination of a frame, a guideframe mounted on the frame and having a plurality of rollers, acylindrical mast passing through the guide frame and engaging therollers, a furrow opener attached to said mast, means for verticallyadjusting the mast, a swinging seat mounted on the frame, a rollersupport for the seat, a track mounted on the frame and supporting saidroller support, a pair of forwardly extending links pivotally connectedwith the seat, lateral members carried by the mast for. rotating thesame, and connections slidably engaged by the links and attached to thelateral members.

In testimony whereof I affix my signature.
